RELATED: Best Fallout 76 World Events, Ranked
Unfortunately, there is no quick answer to the question of what the Mysterious Cave code in Fallout 76 is because it is randomized for each individual player. Thus, fans must obtain the code for themselves, and that is done by collecting six mysterious map fragments from various locations and then placing them on board that is found at the Grafton Pawn Shop.
Updated on July 18th, 2022 by Hodey Johns: When this guide originally debuted, it contained a YouTube link to the location. While some players appreciated this direction, other gamers wanted this guide to show them the exact locations of each map fragment. Now, pictures have been added, showing the exact location of each piece so that gamers can find everything they need all on one page. Also, this latest update moves information about what to do with the map and the cave itself to the end. The information about the code is, therefore, at the start of the guide, making the code easier to find without needing to scroll for the clues.
Mysterious Map Fragment Locations
Here are the locations of the six mysterious map fragments in Fallout 76:
Morgantown High School: Next to a broken terminal on the second floor
Red Rocket Mega Stop: In a station to the southeast on a counter
Haven Church: On a hallway counter
The General’s Steakhouse: On a south-facing bar
Uncanny Caverns: On the welcome building counter
Mothman Museum: On the front desk
Once a player has collected all of the mysterious map fragments, they can then head to the Grafton Pawn Shop and visit the apartment located above.

Inside, fans will find the aforementioned board where they can place the six mysterious map fragments, and they should then switch on the nearby UV light. Doing so will reveal the Mysterious Cave code, and Fallout 76 players can now return to that location, one of Fallout’s most featured spots, and enter it into the keypad.
What’s In The Cave?
With respect to what players will find after entering the Mysterious Cave code, behind the closed door is an elevator that leads to Vault 79. Added as part of a Nuclear Winter patch that was released in October of last year, players could not enter Vault 79 prior to the recently launched Wastelanders update, which gave the vault its interior.
Of course, changes to Vault 79 are far from the only things to be found in Fallout 76’s Wastelanders update, and there is plenty of new content for players to explore. The contents could change again in accordance with how the 5-Year Plan is going.
Fallout 76 is available now for PC, PlayStation 4, and Xbox One.
